Also, the system can determine charge each portable deviceaccording to individual needs and requirements.

The neural network is a multi-layer deep learning network ofinterconnected nodes. Each node can represent a piece of information.Information associated with the nodes is shared among the differentlayers and each layer retains information as information is processed.In some cases, the neural network can include a feed-forward network, inwhich case there are no feedback connections where outputs of thenetwork are fed back into itself. In some cases, the neural network caninclude a recurrent neural network, which can have loops that allowinformation to be carried across nodes while reading in input.

Information can be exchanged between nodes through node-to-nodeinterconnections between the various layers. Nodes of the input layercan activate a set of nodes in the first hidden layer. For example, asshown, each of the input nodes of the input layer is connected to eachof the nodes of the first hidden layer. The nodes of the hidden layercan transform the information of each input node by applying activationfunctions to the information. The information derived from thetransformation can then be passed to and can activate the nodes of thenext hidden layer, which can perform their own designated functions.Example functions include convolutional, up-sampling, datatransformation, pooling, and/or any other suitable functions. The outputof the hidden layer can then activate nodes of the next hidden layer,and so on. The output of the last hidden layer can activate one or morenodes of the output layer, at which point an output is provided. In somecases, while nodes (e.g., node) in the neural network are shown ashaving multiple output lines, a node has a single output and all linesshown as being output from a node represent the same output value.

In some cases, each node or interconnection between nodes can have aweight that is a set of parameters derived from the training of theneural network. For example, an interconnection between nodes canrepresent a piece of information learned about the interconnected nodes.The interconnection can have a numeric weight that can be tuned (e.g.,based on a training dataset), allowing the neural network to be adaptiveto inputs and able to learn as more data is processed.

The neural network can be pre-trained to process the features from thedata in the input layer using the different hidden layers in order toprovide the output through the output layer. In an example in which theneural network is used to identify objects in images, the neural networkcan be trained using training data that includes both images and labels.For instance, training images can be input into the neural network, witheach training image having a label indicating the classes of the one ormore objects in each image (basically, indicating to the network whatthe objects are and what features they have).

In some cases, the neural network can adjust the weights of the nodesusing a training process called backpropagation. Backpropagation caninclude a forward pass, a loss function, a backward pass, and a weightupdate. The forward pass, loss function, backward pass, and parameterupdate is performed for one training iteration. The process can berepeated for a certain number of iterations for each set of trainingimages until the neural network is trained enough so that the weights ofthe layers are accurately tuned.

For the example of identifying objects in images, the forward pass caninclude passing a training image through the neural network. The weightscan be initially randomized before the neural network is trained. Theimage can include, for example, an array of numbers representing thepixels of the image. Each number in the array can include a value from 0to 255 describing the pixel intensity at that position in the array. Inone example, the array can include a 28×28×3 array of numbers with 28rows and 28 columns of pixels and 3 color components (such as red,green, and blue, or luma and two chroma components, or the like).

For a first training iteration for the neural network, the output caninclude values that do not give preference to any particular class dueto the weights being randomly selected at initialization. For example,if the output is a vector with probabilities that the object includesdifferent classes, the probability value for each of the differentclasses may be equal or at least very similar (e.g., for ten possibleclasses, each class may have a probability value of 0.1). With theinitial weights, the neural network is unable to determine low levelfeatures and thus cannot make an accurate determination of what theclassification of the object might be. A loss function can be used toanalyze errors in the output. Any suitable loss function definition canbe used.

The loss (or error) can be high for the first training images since theactual values will be different than the predicted output. The goal oftraining is to minimize the amount of loss so that the predicted outputis the same as the training label. The neural network can perform abackward pass by determining which inputs (weights) most contributed tothe loss of the network, and can adjust the weights so that the lossdecreases and is eventually minimized.

A derivative of the loss with respect to the weights can be computed todetermine the weights that contributed most to the loss of the network.After the derivative is computed, a weight update can be performed byupdating the weights of the filters. For example, the weights can beupdated so that they change in the opposite direction of the gradient. Alearning rate can be set to any suitable value, with a high learningrate including larger weight updates and a lower value indicatingsmaller weight updates.

The neural network can include any suitable deep network. One exampleincludes a convolutional neural network (CNN), which includes an inputlayer and an output layer, with multiple hidden layers between the inputand out layers. The hidden layers of a CNN include a series ofconvolutional, nonlinear, pooling (for downsampling), and fullyconnected layers. In other examples, the neural network can representany other deep network other than a CNN, such as an autoencoder, a deepbelief nets (DBNs), a Recurrent Neural Networks (RNNs), etc.

Neural network can also be used to perform deep learning. In thisexample, the neural network includes an input layer, a convolutionalhidden layer, a pooling hidden layer, fully connected layers, and outputlayer. The neural network can identify specific environmental features(e.g., humidity, temperature, amount of charge, number of portabledevices, etc.) in an image. First, each feature is considered as aneuron that has learnable weights and biases. Each neuron receives someinputs, performs a dot product and optionally follows it with anon-linearity function. The neural network can also encode certainproperties into the architecture by expressing a single differentiablescore function from the data on one end to class scores at the other toextract specific environmental features from the target image. Afteridentifying features as specific environmental features, the neuralnetwork can generate a mean score (or z-score) of each feature and takethe average of the scores within the user-defined buffer.
